Continental Grand Prix 4000 S 23-622 mm black
Continental Grand Prix 4000 S
The all black Grand Prix 4000 S catches the eye with its big silver labels. It matches every high-end racebike perfectly and can do more than just look good. With the new Black Chili Compound rolling resistance is reduced by 26%, grip is increased by 30% and mileage is increased by 5%.
The new compound
How are these figures possible..? The carbon filler particles within the rubber compound are reduced to 1/10th of the size of standard carbon particles. This creates a closer knit with the particles having more points of contact with each other, thus forming a tighter bond, (increasing mileage performance) and also with the road (increasing grip). Also the way in which the particles interact with each other has a dramatic effect on reducing rolling resistance. Black Chili is used by several ProTour teams in 2007.
